Super
effective, Low-Noise-Preamplifiers with VOX
The preamplifiers of the Super-Amp series are available for the amateur radio
bands 6 m, 2 m, 70, 23 und 13 cm. All models are equipped with super-low-noise,
large-signal-resistant semiconductors which are safeguarded against HF by a an effective
protective circuit. To suppress unwanted signals, high quality Helix filters are
used.
The Super-Amp amplifiers can be operated alternatively with a remote or direct
feed. When a power amplifier is used, we recommend our Sequence Controller of
the "DCW" product line. This ensures a timely sequential
receive/transmit switchover, controlling the relays load-free, without HF.
The Super-Amp amplifiers are equipped with an UV-resistant, weatherproof
housing and N-sockets. Hot-dip galvanized clamps and installation material are
part of the delivery.
